BATTLE CREEK, MICHIGAN, ASSIGNORS T0 XELLOGG COMPANY, OF BATTLE CREEK, MICHIGAN, A CORPORATION OF DELAWARE rmsixaenni` momma Application led December 14, 1923. Serial No. 6801564.

This invention relates to a packaging machine and aims to provide a device yof this character primarily adapted for use in connection with the packaging of materials, particularly food stuffs such as, for example, corn flakes, bran, etc.

' It is an object of the present invention to provide a packaging machine which will be Y structurally superior and functionally advantageous in comparison with machines having somewhat similar objects.

A further object resides in the construction of a machine adapted to close material containing packages without injuring the material during the various manipulations to which the package is subjected.

A still further object is the construction of a machine preferably embracing a number of units, the functions of these units being such that an article manipulated thereby will be eiiciently operated on.

Another object of the present invention .is the provision of an apparatus which will be automatic in operation and which, when utilized in conjunction with packages of the type hereinafter referred to, will not alone close the same but will also seal the parts to prevent the entrance' of air, moisture, etc.

Still another object is that of furnishing a machine of the type described, preferably embracing a number of units which unitsmay be used to advantage either independent-ly or in combinations other than that shown in the illustrative embodiment hereinafter referred to.

Other objects of the invention will in part be obvious and will in part appear herein/- after.

The invention accordingly comprises the features of construction, combinations of elements, and arrangement of parts, which will be exemplifiedin the construction hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following. detailed description taken -in connection with the accompanying drawings, in which:

' According to the embodiment of the invention illustrated in the present application, a machine is provided which is particularly adapted to receive a box of cardboard or similarmaterial having its base closed and its upper end opened, and having at its upper end a numberI of flaps which are adapted to be folded in a manner to provide an adequate seal. Y Disposed within the box is a bag or liner of suitable material such as, for example, wax impregnated paper, having its neck or mouth unsealed and being filled with a loose substance which is to be packaged. It is to be understood that the operations of forming the box and the bag or liner, filling the latter with the material to be packaged, and disposing the same within the box either before or after the filling operation, may be accomplished by means of a of the detail of machine or machines arranged in advance of that which forms the subject matter of the present application, or obviously, these operations, orcertain of the same, may be performed by hand.

Conceding that articles of the nature afore-described are introduced into a machine embod ing the construction, herewith describe and illustrated, the material or substanc within the box will be first properly distributed or stowed and subsequently the mouth of the bag or liner will be sealed and disposed within the body of thevbox after which the flaps of the latter will be folded upon themselves to in turn seal this portion of the package and the sealed box containing the sealed bag within which the material is packed will be automatically delivered from the end of the machine thereby effecting great saving in expense, labor andtime.

For the sake of avoiding confusion, the succeeding description has been divided into chapters, each referring to one of the particular units of the mechanism by means of which, at a predetermined station in the path of travel of the package, certain operations are performed tending towards the closing or sealing of the package and the final delivery thereof. With this in mind, the description immediately following will deal with the construction and operation of the mechanism whereby the package is introduced into the machine proper and by means of which the substance contained within the said package will be disposed to permit of the subsequent sealing operations.

In order that the carton or similar package may be more easily followed in its course through the machine in the following description, and that successive operations thereon by the different mechanisms may be more clearly understood, this carton is designated as a whole throughout the different views of the drawings and in the following detailed description by P. Also the leading ap of the carton as the latter progresses through the machine is designated P1, the following Hap by P2 and the op osing lateral fiaps P3 and P4 respectively. he liner for the carton is also designated in the several views by the reference numeral R.

Package spacing and content sto/wing mecham'sm (sta-tions A and B) Referring to Figs. 1, 2, and 3, it will be perceived that atthe front end of the machine there is provided a conveyor belt 40 which may be mounted for movement in a plane corresponding to that in which the bed of the machine is disposed. This conveyor may be connected with, or forma part of a machine in which the liners or bags are filled, and adjacent the entry end of the present machine spaced guides 41 and 42 are provided, arranged one at each sidel of the conveyor and
